This application is related to U.S. patent application Ser. No. 16/283,426, entitled “CONTROLLING AN ELECTRONIC GAMING MACHINE TO PROVIDE A “PRIZE ON” SYMBOL TRIGGER,” to U.S. patent application Ser. No. 29/681,215, entitled “DISPLAY SCREEN OR PORTION THEREOF WITH TRANSITIONAL GRAPHICAL USER INTERFACE,” U.S. patent application Ser.

FIG. 1 is a first image in a sequence of a display screen or portion thereof with transitional graphical user interface showing our new design;

FIG. 2 is the second image thereof;

FIG. 3 is the third image thereof;

FIG. 4 is the fourth image thereof;

FIG. 5 is the fifth image thereof;

FIG. 6 is an enlarged view of a portion of the display screen or portion thereof with transitional graphical user interface of FIG. 1, shown separately for clarity of illustration;
